"The Lumex CSS is a turnkey solution . To be clear, ARM isn't about to start selling chips. Instead, it has crafted production-ready implementations for the 3nm semiconductor nodes of multiple foundries. In ARM's own words, its silicon and OEM partners will be able to "use the implementations as flexible building blocks, so they can focus on differentiation at the CPU and GPU cluster level.""
"So, there is no fixed design, however, the new parts are highly customizable. The new C1-DSU enables designs from 1 to 14 CPU cores with up to three core types choosing from four options, the C1-Ultra, C1-Premium, C1-Pro and C1-Nano that we discussed in the other article. For the GPU, the Mali-G1 scales from 1 to 24 shaders. The Lumex CSS platform ARM has "secret sauce" to make the Lumex better than custom chipset designs that have come before."
ARM created the Lumex compute subsystem (CSS) as a turnkey set of production-ready implementations for multiple foundries' 3nm nodes. The platform provides configurable C1 CPU clusters—C1-Ultra, C1-Premium, C1-Pro, C1-Nano—targeting performance, area efficiency, sustained efficiency, and ultra-low power use cases. The C1-DSU supports designs from 1 to 14 CPU cores and mixes up to three core types; the Mali-G1 GPU scales from 1 to 24 shaders. The Lumex CSS adds a System Interconnect L1 with system-level cache and 71% leakage reduction versus standard RAM to cut idle power. An MMU L1 enables secure, cost-efficient virtualization.
